Short version: The Tuya WiFi Zigbee PIR Motion Sensor is a small, battery-powered device that detects movement in your home. The Zigbee version works well with Home Assistant for local control, meaning it does not need the internet to function. However, the biggest challenge is that the listing often sells both Wi-Fi and Zigbee versions, so you must choose carefully to get the one that works best with Home Assistant.

What the Tuya WiFi Zigbee motion sensor is
This product is a Passive Infrared (PIR) motion sensor. A PIR sensor detects changes in infrared radiation, which is heat. When a person moves into its detection area, their body heat causes a change that the sensor notices. This is how it tells if someone is in the room. The listing says it is designed for home safety and real-time monitoring.
In the box, you typically get the motion sensor unit itself and maybe some adhesive tape or a bracket for mounting. This sensor is small and meant to be discreet. It runs on a CR2450 coin cell battery, which is a bit less common than AA or AAA batteries. The battery powers the sensor for a reported 6-12 months, but this can vary based on how often it detects motion and how strong your Zigbee network is. Some listings mention a USB power option, but the standard model is battery-operated.
Crucially, this sensor comes in two main versions: Wi-Fi and Zigbee. The Wi-Fi version connects directly to your home Wi-Fi network. The Zigbee version uses a different wireless technology called Zigbee, which creates a mesh network. A mesh network means that devices can talk to each other and pass messages along, extending the range of your smart home. For Home Assistant users, the Zigbee version is generally preferred because it allows for local control, meaning it does not rely on cloud servers.
Home Assistant compatibility
For the Zigbee version of this Tuya motion sensor, you will need a Zigbee coordinator. A Zigbee coordinator is a USB stick or a built-in radio that lets your Home Assistant computer talk to Zigbee devices. Without it, Home Assistant cannot communicate with Zigbee sensors directly. If you accidentally buy the Wi-Fi version, it will typically only work through the Tuya Smart or Smart Life app, and then you would use the Tuya cloud integration in Home Assistant.
| Option | Works? | Notes |
|---|---|---|
| ZHA | Likely | Supported if it is a standard Tuya Zigbee device. Always check the model number on the box against the ZHA device list. |
| Zigbee2MQTT | Likely | Many Tuya Zigbee motion sensors are supported. Check the specific model number on the Zigbee2MQTT supported devices list before buying. |
| Tuya (cloud integration) | Yes | Works for both Wi-Fi and Zigbee versions after setup in the Tuya Smart or Smart Life app. Requires internet access. |
| Matter | No | This device does not support Matter, which is a newer smart home standard. |
| Local or cloud | Local | The Zigbee version works locally with ZHA or Zigbee2MQTT. The Wi-Fi version or using the Tuya integration relies on the Tuya cloud. |
Who it is for
This Tuya motion sensor is a good fit for Home Assistant beginners who are looking for an affordable way to add basic motion detection to their smart home. If you already have a Zigbee network set up with a coordinator like a SONOFF Zigbee 3.0 USB Dongle Plus, this sensor can easily join your existing mesh. It is also suitable for those who need a small, unobtrusive sensor that can be placed in various spots without being too noticeable. People who are comfortable checking product details, like model numbers and Zigbee certification, will have the best experience.
You might want to skip this sensor if you prefer a truly plug-and-play experience without worrying about Wi-Fi versus Zigbee versions. If you need advanced features like true human presence detection, which tells you if someone is still in a room even if they are not moving much, this PIR sensor is not enough. For presence detection, you would need a different type of sensor, like a mmWave sensor. Also, if you want to avoid Tuya’s ecosystem entirely or do not want to deal with less common battery types, you might look for alternatives.
How to set it up in Home Assistant
Setting up the Zigbee version of this motion sensor in Home Assistant usually involves these steps. We will assume you are using Zigbee2MQTT, which is a popular way to manage Zigbee devices through Home Assistant.
- First, make sure your Zigbee coordinator is properly set up and running with Zigbee2MQTT in Home Assistant. You need a functioning Zigbee network to add new devices. You can find tips for optimizing your Zigbee and Thread mesh network if you are having issues.
- In Home Assistant, go to Settings, then Devices & services.
- Find your Zigbee2MQTT integration and click on Configure.
- In the Zigbee2MQTT interface, look for an option like Permit join (All) and enable it. This opens your Zigbee network for new devices to connect.
- Now, take your Tuya motion sensor. You will need to put it into pairing mode. This usually involves holding down a small button on the device for 5-10 seconds until an LED light starts blinking. The exact method can vary, so check any small instruction sheet that comes with the sensor.
- Once the sensor is in pairing mode, Zigbee2MQTT should detect it. You will see a notification in Home Assistant that a new device has been discovered.
- Click on the notification to add the device. You may be able to rename it and assign it to an area in your home. After this, the sensor will appear as a new device with its own entities, such as a motion sensor entity and possibly a battery level entity, in Home Assistant.
Common issues and variants to avoid
- Wi-Fi vs. Zigbee confusion: The most significant issue is that many AliExpress listings for this product include both Wi-Fi and Zigbee versions. Always double-check the product title, description, and especially the variant selector before adding to your cart. Look for keywords like ‘Zigbee 3.0’ or ‘Tuya Zigbee Gateway Required’. If it mentions ‘Tuya Wi-Fi’ or ‘No Gateway Required’, it is likely the Wi-Fi version.
- Model number verification: Even if a listing says ‘Zigbee’, it is wise to try and find the exact model number. Then, cross-reference this number with the Zigbee2MQTT supported devices list or the ZHA documentation. This helps confirm compatibility before you buy.
- Battery life expectations: While manufacturers often claim long battery life, real-world performance can vary. Factors like the number of detections per day, the quality of your Zigbee mesh network, and cold temperatures can reduce battery life. Be prepared to replace the CR2450 battery every 6-12 months, or even sooner.
- False positives and detection zones: PIR sensors can sometimes trigger on pets or sudden changes in light or temperature. Pay attention to where you mount the sensor to avoid these issues. Also, understand that PIR sensors have a specific detection angle and range, which means they might not cover an entire large room effectively without careful placement.
- Not a presence sensor: This is a motion sensor, not a presence sensor. It detects movement, but if a person sits still for a few minutes, the sensor will report no motion. If you need to know if a room is occupied even when someone is motionless, you need a different technology like mmWave radar. We have a guide on Best Presence Sensors on AliExpress if that is what you are looking for.
Should you buy it?
The Tuya WiFi Zigbee PIR Motion Sensor is a solid choice for Home Assistant users who need basic motion detection and are comfortable verifying the correct Zigbee version. Its low price makes it an attractive option for expanding your smart home’s sensing capabilities without spending a lot. However, the mixed-version listings mean you must be careful during purchase to ensure you get the Zigbee model for local Home Assistant control.
If you prioritize ease of purchase and guaranteed Zigbee compatibility without the hassle of checking variants, you might consider alternatives like the SONOFF SNZB-03P Zigbee motion sensor, which typically has clearer product listings. But for those on a budget who are willing to do a little research, this Tuya sensor can be a valuable addition to a Home Assistant setup.
